SPECIFICATION forming part of Letters Patent No. 240,8 O,da.ted April 26, 1881.

l Application filed March 30, 1881. (No model.) v v To all whom it may concern Be it known that I, SAMUEL WI SLOW, a citizen ofthe United States, residingatWorcester, in the codnty of Worcesterand State of Massachusetts, have invented new and useful.

provide. for the ready removal. and replacementiof the rollers, and secure a'strong and steady bearing for the rotary roller-axles.

In-the accompanyiiig drawings, Figure l is a perspective view of a roller-skate const'ructed according to my invention,and having one, V roller of each pair removed- Fig.2 is a iongij zo tuldinal vertical section through the centerline not the skate. Fig. 3 is a view of the hangers, swiveling roller-standards, and elastic bearin gblock detached. t v

The letterA denotes the foot-piece; pro- 5 arranged transversely under the heel and toe portions of the foot-piece, and saidaxles turn loosely in elongated tubular bearings D, from which rise standardsd, carrying at their tops inclined sleeves E, arranged at right angles to the said tubular bearings. formed at or about the center of the tubular bearings toform. a chamber for holding a lubrieating medium. These sleeves E have attached to theirtops'flat plates F, the upper surfaces of which are also inclined long'itudL nally with respect to thefoot-piece, but not quite so much so as the sleeves E. The plates 1* are, in efiect, flat upper surfaces for the sleeves. From the opposite edges ofthe plates P m-ear their outer ends, respectively, project lugs G G, for a-purpose to be hereinafter explained.- The sleeves E are swiveled upon inclined pins h, the innerand lowerends of which are supported in bearings at the lower ends of long hangers I I projecting downward from suitable fastenin g-plates, 70, attached to the bot V tom of the foot-piece, and the upper and outer 5o ends of said pins are Secured in cars 1 projectin g from plates is, also attached to the hot- Of roller:-

rocking motion, and is Provided with two pairs vided with heel and toe-straps, asusual. The rollers B are mounted loosely on axles O O,

A recess should be tom of thefoot-piece. "The fastening-platesk and k at 'eacheud of the foot-piece are formed with-recesses l l, which receive the opposite ends of an elastic block, m,ofindia-rubber, and hold said block in position against the bottom of the foot-piece directly above the plate F,

said block being somewhat of-a Wedge shape, in order that its under surface may snugly fit upon the surface of the plate;

The yielding of the roller-blocks permits the pins h to turn in the sleeve E, and thus a sidewise rocking movement is obtained for the foot-piece when extra pressure is exerted upon either side, while at the same time said footpiece is provided with an elastic support tending to hold it erect, but allowing it to yield to accommodate the movements of the skaters foot. 4

Totvoiauargror thefoot piece rocking too far to either side, and, twisting or unnecesranged to strike the plates and limit the distance to which the foot-piece may turn.

, The elongated tubular bearings I) give the skate a very steady movement and afford a lesarily straining the ankle, thelugs G Gare ar verage which" enables the skater to turn the foot-piece with but very little efl'ect, so that curvesmay be turned with great ease.

The axles are held in their bearings and the rollers upon the axles bylordinaryspring-linchpins, and as these parts can all be taken apart by simplyremoving the linchpins, it will be' seenthat a worn out or broken roller may be removed and replaced by a new one without trouble. v

1 am aware that, the foot-piece of a rollerskate has been arrangedto have an elastic rocking motion, and have myself shown in aprior patent a rubber blockarranged between the flat face of a'hanger and'a swiveling rollercarrier, and I lay no claim here to such inventions. a

What I claim-is 1. I na roller-skate, a swiveling roller-carrier provided with laterally-projecting lugs arot the fo0t-picce and limit the rocking motion of said foot-piece, substantially as described.

2. In a roller-skate, the suitably-supported ranged to strike suitable stopsupon the bottom swiveling sleeve E, having a flat upper sur' i face, and provided with legs G G, arranged to e '7 i a .eaeisee strike suitable stepson the bottom of the foot- 4. In a. roller-skate, the separate plates, is k, piece, in combination with the rubber block I carrying theswivel-bin supports, and provided arranged between said flat upper surface and with the recesses to receive the ends of the x the bottom of the foot-piece, substantially as rubber bloeks,-substantially"a described. 5 described, and for the purpose set forth.
